    Hi!
    
 
    If ADV7612 receive the HDMI with High-Resolution Audio ,
    
 
    can the device output the High-Resolution Audio with I2S ?
    
 
    * High-Resolution Audio (Higher than 24bit/96kHz)
    
 
    If it can output High-Resolution Audio, does the device sustain the dat rlate?
    
 

    
 
    And could you tell me the I2S maximum date rate?
    
 

    Thank you.
    
 
    Best regards.

    The ADV7612 can extract L-PCM, IEC 61937 compressed or DST audio data from the audio packets.  These standards set the limits.  It can support sampling frequncies up to 192kHz.  Sample width is limited to 24 bits.

      Hi!
      
 
      GuenterL.
      
 
      Thank you for your answer.
      
 
      I have an another question.
      
 
      At the reference manual, it says that
      
 
      the I2S max bandwidth is 31bits.
      
 
      
 
      And your answer was 24bits.
      
 
      The setting top is 31bit, but is it interpretation to be usable only to 24bit?
      
 
      Thank you.
      
 
      best regards.

        Audio standards only require 24 bit.  Refer to IEC60958 and IEC61937 to how the audio is encoded.  A lot depends on output format you need.
